On the great feast of St. Catherine of Siena, Doctor of the Church, we ponder how Divine Mercy was of central importance for her and St. Thomas Aquinas. May we ask both of these powerful saints for their intercession today, that we too may live lives of ardent prayer and great confidence in Divine Mercy. #ThomisticInstitute #SaintCatherineofSiena #DivineMercy #CatholicTheology
